SIGNAL BOX.

Application filed January 20, 1922. Serial No. 580,876.

To all whom it may concern:

Be it known that I, HERBERT D. LUKER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Signal Boxes, of which the following is a specification.

The present invention relates to signal boxes especially useful in connection with 1 automobiles and has for itsprincipal object to combine a lighting system with the signal box which will allow an automobile to be parked with comparative safeness along the road, the light being so arranged as to be distinctly seen by an oncoming vehicle.

Another important object of the invention is to construct a signal box which will be attractive in appearance, economical to manufacture, and well adapted to the purpose for which it is designed.

With the above uni numerous other objects in view, the invention resides in certain novel features of construction, and the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing I Figure 1 is a front elevation of the preferred embodiment of the invention,

Figure 2 is an end elevation thereof,

Figure 3 is a vertical section taken on the line 3--3 of Figure 1,

Fi re 4.- is a horizontal section taken on the line 4-4 of Figure 1 looking in the direction of the arrow, 7

Figure 5 is a bottom lan thereof,

Figure 6 is an end 0 ovation of a modification, a rtion thereof being shown in all section, and

Fi re 7 is a detailed section taken on the hue 7-7 of Figure 6.

Referring to the drawing in detail it will be seen that the preferred embodiment of the invention consists of a back plate 1 thetop end of which is tapered and provided with an aperture for receiving a trans parent concave-convex panel 2. A cover 3' is attached along one edge to the plate 1 so as to remive a socket indicated at 4. An auxiliary plate 5 is attached to'the cover 3 and extends" parallelwith the upper end of the plate 1 and in spaced relation thereto and is tapered so as to conform in shape with the upper end of the plate 1 and the cover 3. This auxiliary plate 5 is preferably formed integral with the cover 3 and is extended at right an les as shown at 6. A. transparent panel 7 similar tothe panel 2 is provided in its aperture so as to register with the panel 2. Side pieces 8 depend from the ends of the extension 6 and a bottom piece 9 extends between their bottom ends. A transparent plate 10 is situated between the members 6, 8 and 9 and extends diagonall from the outer edge of the member 9 to t e inner edge of the member 6 and is held in place by the cleats 11. A wall member 12 is disposed so as to form a continuation of the auxiliary plate 5 and is attached at its bottom end to the bottom piece 9. By this construction it will be seen that a compartment 14 is formed which is in com munication with the compartment 15 so that the light in the com artment 15 ma be delivered down towar the ground. is signal box is preferably mounted on the lefthand rear mud guard and therefore the light will be rejected downwardly on the road so that die mud guard upon which it is mounted ma readily be seen by drivers of oncoming vehicles so that they may easily pass the parked vehicle without guessing at its exact location asis quite frequently the case under present circumstances. This signal box also provides the compartment 16 formed by the bottom piece 9, transparent plate 10 and wall 12. A plurality of illuminating means 17 are mounted in the com artment 16 and the transparent plate 10 is provided with suitable signalling words or letmrs as shown to advantage in Figural. The compartment 16, of course, my be divided into sub-compartments by w is 18 whereby difierent signals ma be provided as is shown to advantage in igure 1.

In the modification shown in Fi re 6 I provide a vertical transparent p ate 10' which is held in place by the cleats 11' and the flanges 12 along the top piece 6, bottom piece 9, and one of the side pieces 8. 0n the other side piece I provide a removable angle iec'e 20 held in "lace b screws 21 s that t e transparent p ate 10 may be slid out of the when it is at desired.

Having thus described my invention what I claimas new is i In a signal box, a casing including side walls, a top wall, a bottom Wall, and a rear wall, the'side, top and bottom walls terminating in the same plane and extending outwardly from the rear wall, a transparent inclined panel disposed in the casing extending from the forward edge of the bottom wall to the rear edge of the top wall and arranged between the side walls, and a light in said compartment disposed in. rear of the panel.

In testimony whereof I aflix my signa ture.

HERBERT D. LUKER.
